Taylor Swift needs to stop having so many friends. The latest to join her reign of terror is Lisa Kudrow, Justin Timberlake and Selena Gomez. Taylor sang 'Smelly Cat' with Friends Star Lisa Kudrow. Taylor introduced actress Lisa Kudow as her Friends character Phoebe. She asked the audience to be kind as Phoebe was not used to playing such large venues. They jammed and Phoebe even had some notes for Taylor. This has to be our favourite Taylor moment to date. Not satisfied with that she called on Justin Timberlake to take the stage. They sang his song 'Mirrors'. It was kinda amazing but no 'Smelly Cat'. Check it out here. If that is not enough for you, Taylor then brought in Selena for a rendition of 'Good for You'. This is viewable here. But really the highlight is 'Smelly Cat'.
